Answer:
So the thesis is that "School uniforms are the better choice for three reasons"
Answer:
A
Explanation:
You can choose between A or D depending how you "like it" but A is the correctly written one
A and B are not run-on sentences because A doesn't even have a comma in it. And B has a semicolon. Something that would prevent a run-on sentence.
It comes down to C or D. D has a nonrestrictive clause.
My finally answer comes to C.
